i965: Implement INTEL_performance_query backend

This adds a bare-bones backend for the INTEL_performance_query extension
that exposes pipeline statistics.

Although this could be considered redundant given that the same
statistics are already available via query objects, they are a simple
starting point for this extension and it's expected to be convenient for
tools wanting to have a single go to api to introspect what performance
counters are available, along with names, descriptions and semantic/data
types.

This code is derived from Kenneth Graunke's work, temporarily removed
while the frontend and backend interface were reworked.

mesa: Model INTEL perf query backend after query obj BE

Instead of using the same backend interface as AMD_performance_monitor
this defines a dedicated INTEL_performance_query interface that is
modelled more on the ARB_query_buffer_object interface (considering the
similarity of the extensions) with the addition of vfuncs for
initializing and enumerating query and counter info.

Compared to the previous backend, some notable differences are:

- The backend is free to represent counters using whatever data
  structures are optimal/convenient since queries and counters are
  enumerated via an iterator api instead of declaring them using
  structures directly shared with the frontend.

  This is also done to help us support the full range of data and
  semantic types available with INTEL_performance_query which is awkward
  while using a structure shared with the AMD_performance_monitor
  backend since neither extension's types are a subset of the other.

- The backend must support waiting for a query instead of the frontend
  simply using glFinish().

- Objects go through 'Active' and 'Ready' states consistent with the
  query object backend (hopefully making them more familiar). There is
  no 'Ended' state (which used to show that a query has ended at least
  once for a given object). There is a new 'Used' state, set when a
  query is first begun which implies that we are expecting to get
  results back for the object at some point. There's no equivalent to
  the 'EverBound' state since the spec doesn't require there to be a
  limbo state between generating IDs and associating them with an object
  on query Begin.

The INTEL_performance_query and AMD_performance_monitor extensions are
now completely orthogonal within Mesa main (though a driver could
optionally choose to implement both extensions within a unified backend
if that were convenient for the sake of sharing state/code).

v2: (Samuel Pitoiset)
- init PerfQuery.NumQueries in frontend
- s/return_string/output_clipped_string/
- s/backed/backend/ typo
- remove redundant *bytesWritten = 0
v3:
- Add InitPerfQueryInfo for lazy probing of available queries
v4:
- Clean up some internal usage of GL typedefs (Ken)

To allow the backend interfaces for AMD_performance_monitor and

specific requirements of each extension this starts by separating
the frontends of these extensions.

Even though there wasn't much tying these frontends together, this
separation intentionally copies what few helpers/utilities that were
shared between the two extensions, avoiding any re-factoring specific to

gallium/vl: Simplify usage of full range matrices

When looking at the full range matrices, it becomes obvious that the difference
between the standard matrices and the full range matrices is that the full
range matrices are multiplied by 1.164. Together with offsetting the y value
with -16/255, this will scale and offset RGB with the desired quantities.

However, the standard SMPTE 240M matrix seems to differ a bit since the
U and V coefficients are only multiplied with 1.138 to get the full range
matrix. This would actually alter the color somewhat so I figure that's an
error. The full range matrix is consistent with Nvidia's VDPAU implementation.

We can also incorporate the ybias in the brightness simplifying the
calculation somewhat.
